CLOTH-CUTTI NGY MAel-ir-N SPECIFICATION forming part of Letters PatentNo. 457,431,- dated August I1, I891.

Application filed May 18, 1891- Serial No. 393,142. (No model.)

- To all whom it may concern;

Be it known that I, DAVID ROCHE, a subject of the Queen of GreatBritain, residing at the city of Cleveland, in the county of Ouyahogaand State of Ohio, have invented certain new and useful Improvements inMachines for Cutting Cloth, of which the following is a full, clear, andexact description,ref-

erence being had to the accompanying drawings, in which Figure 1 is aplan view of said machine. Fig. 2 is a side elevation of thesame, andFig. 3 is a transverse sectional view on the line 3 3.

The principal object of my invention is to provide a machine especiallyadapted to cut narrow bias strips of velveteen smoothly, of uniformwidth, and with great rapidity.

My invention consists in the construction and combination of the partshereinafter described, and definitely pointed out in the claims.

I will now proceed to describe the machine illustrated in the drawings,referring to the parts by letters.

A A represent the side rails of the frame, and B Brepresent transverserollers, which are journaled in boxes 6 17, secured to said side rails.

b I) represent brackets, which are secured to one end of the frame, oneon each side thereof. To each of these brackets are secured the two arms0 O.

D represents a transverse shaft journaled in the ends of the upper arms0 C, and E represents a transverse shaft directly below the shaft D,which is journaled in the ends of the lower arms O G.

On the shafts D and E are keyed the interlocking gears d e, bymeans ofwhich one shaft is driven by the other in the opposite direction and atthe same rate of speed. On the end of one shaft are the fast and loosepulleys e 6 upon which a driving-beltmay run.

To each of the shafts D E are rigidly secured a number of circularknives F and G. Each knife F is in such relation to a correspondingknife G, substantially as shown, that a fabric drawn between the knivesis cleanly sheared thereby. The distance between the shearing-edges ofeach pair of knives corresponds to the width of the strips it is desiredto cut. 7

H represents a reciprocating table, which rests upon the rollers B B,and is guided in its back and forth movement by the side rails. Thistable is provided with as many longi tudinal slots as there are knivessecured to the lower shaft, and said knives project and operate throughsaid slots, As the machine which is illustrated in the drawings isconstructed, this table is made of longitudinal strips 77., of wood,slightly narrower than the distance between two adjacent knives, whichstrips are secured at their ends to the crosspieces h 72. respectively,and at a distance apart sufficient to accommodate the knives.

I represents a frame composed of similar slats so placed that the knivessecured to the upper shaft may pass between them. At one end these slatsare secured to a cross-piece 'i', while at the other end each slat ishinged by means of flexible hinges (as leather hinges) to thecorresponding slat h of the table.

J J represent two levers pivoted to some stationary part of the frame,one on each sideof the machine.

K represents a roller journaled in the forward ends of said levers, andL L represent two expanding coil-springs which are compressed betweenthe brackets b and the rear ends of said levers J. These springs forcethe roller K downward onto and in contact with the frame I when themachine is in operation. One of the rollers B is placed just below theroller K, substantially as shown, wherefore the table and frame arepressed between said roller 13 and roller K.

In operating the machine the table is first.

drawn to the left until the frame I is freed from engagement with theroller K. Then said frame is swung upward and held up until the fabrichas been placed upon the table.

Five or six thicknesses of the fabrics maybe"- any suitable catchas,for-example,-the spring h The knives F and G having been set inrevolution in the direction indicated by the arrows, the table is pushedto ward the knives. Before the fabric reaches the knives said tablepasses between the rollers K and B, and

said roller K, by pressing upon the frame I,

prevents any displacement of the fabric by the knives. The table may bemoved by hand both backward and forward, although suitable mechanism maybe provided to produce this movement, if desired. As the fabric isforced between the the shearing-knives it is cut lnto strips of a widthsubstantially equal to the distance between the shearing-edgesof ada-cent pairs of knives. The table is then drawn back to the positionshown, where the cross-piece 72/ engages with the stops 12 after whichthe operation above described is repeated.

IfIaving thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a longitudinally-slotted reciprocating table, alongitudinally-slotted frame, and means for fastening said frame to thetable, with two revoluble shafts, one above and one below said table,two series of circular knives secured to said shafts and projectingthrough said slots into shearing relation wit-h each other,substantially as and for the purpose specified.

2. The combination of the frame of the machine and transverse rollersjournaled therein, a longitndinally-slotted table restingupon said.rollers, and a longitudinally slotted frame suitably secured to saidtable, with the spring-actuated pressure-roll K, the two transverseshafts D and E, each having secured thereto 'a series of circularknives, and means for revolving said shafts,substantially as and for thepurpose specified.

The combination of the frame and transverse rollers j ournaled therein,the longitudinally-slotted table, and a longitudinally-slotted framecomposed of slats, each one of which is separately hinged to acorresponding slat in the frame, and a spring-catch with which the otherend of said frame maybe connected with the table, with the two pivotedlevers J J, a transverse roller journaled in said levers, and thecoil-springs LL, compressed between the other ends of said levers andthe frame of the machine, with two transverse shafts, interlocking gearssecured to said shafts, and a series of circular knives secured to eachshaft, substantially as and for the purpose specified.
